General Information about Regal Blue

It belongs to the blue color family and is characterized by its relatively low saturation and luminance. In the RGB color model, it is composed of 0.8% red, 23.1% green, and 45.1% blue.

It's a versatile color that can be used in a variety of applications, from web design and branding to fashion and interior decor. However, its dark nature requires careful consideration of contrast and accessibility when used in text or interactive elements.

The color #023B73, also known as Regal Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value (approximately 3.5) results in a poor contrast ratio against typical light backgrounds like white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for readability. For body text, a contrast ratio of at least 4.5:1 is recommended, while for large text (14pt bold or 18pt regular) a ratio of 3:1 is required. Regal Blue fails to meet these standards against white. To improve accessibility, consider using Regal Blue sparingly for decorative elements or pairing it with much lighter colors for text and interactive elements. Aim for a contrast ratio that meets or exceeds WCAG guidelines, ensuring that content is perceivable and usable for all users, including those with low vision or color deficiencies. Tools like contrast checkers can assist in evaluating color combinations.
